Difference between 301 and 302
Both redirect visitors, but they communicate different intent. A 301 is permanent, while a 302 is temporary.
Recommended default for merchants
For most Shopify URL updates, use 301 because product and collection changes are usually permanent.
Temporary campaign use cases
Use 302 when a promotion page is active for a short period and you plan to restore the original route later.
SEO impact by redirect type
Search engines treat 301 as a permanent signal and may transfer more ranking value over time.
How to switch redirect type safely
Document the original intent and set a reminder date so temporary redirects are reviewed.
